negative charges separated by a
distance of 1augustro.
b)what is the magnitude of gravit'l
force between the negetive charges
(electro)?
c) determine the ratio of the gravt'l
force and electrostatic force.
(Help with even the formulae!)
To find the magnitude of the electrostatic force between two negative charges, we can use Coulomb's Law. Coulomb's Law states that the magnitude of the electrostatic force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
a) To find the magnitude of the electrostatic force between the negative charges, we need to know the value of the charges. Let's assume the charges are q1 and q2. The distance between them is given as 1 augustro.
The formula for Coulomb's Law is:
F = k * (|q1| * |q2|) / r^2
Where:
F is the magnitude of the electrostatic force,
k is the electrostatic constant (k = 8.99 x 10^9 N m^2/C^2),
|q1| and |q2| are the absolute values of the charges, and
r is the distance between the charges.
Substituting the given values:
q1 = -e (negative charge)
q2 = -e (negative charge)
r = 1 augustro
The magnitude of the electrostatic force can be calculated as:
F = (8.99 x 10^9 N m^2/C^2) * ((|-e|) * (|-e|)) / (1 augustro)^2
b) The magnitude of the gravitational force between the negative charges can be determined using Newton's Law of Universal Gravitation. However, it seems there is a misunderstanding in your question. Gravitational force is only present between objects with mass, not charges. So, the magnitude of the gravitational force between the negative charges would be zero since charges do not have mass.
c) Since there is no gravitational force acting between the negative charges, the ratio of the gravitational force to the electrostatic force is undefined or zero in this context.
